Mammals have sweat glands, hair and feed their young though milk-producing glands. Humans are mammals.

Some are native (here since the last Ice Age, 13,000 years ago) and some have been introduced by Man. A few species escaped from captivity and are now breeding successfully in the wild (feral). The term 'mysterious' seemed apt for the project as the mammals of Ireland have presented us with many intriguing problems.
For example, when and how did they arrive on the island of Ireland? In a modern context, their distribution is frequently a mystery, mainly because
